Do we have all of these kind of failures in San Francisco . Unfortunately, we have them all. The rock from here is used from the sea wall. It came from this hill. It was a itgnoll that was present. Because of this blasting that occurred, the rock is weak. While most of the time, there are times of heavy rain. Sometimes, this has nothing to do with the rainfall. Iraq is 50 to an old and then it just falls. In this particular area where were standing, we have seen the wall at the base. The big steel beams with the fence. This is an effective way of preventing the rock that does fall from causing damage. That might protect the bottom of the hill but it doesnt do anything over the hill. It has long been my understanding that the city of San Francisco says and the Building Department takes this position that there is no one buildable lot unbuildable lot. I wonder if this is realistic. If money is an issue, we can develop solutions that will mitigate the impact. That a solution can be elimin
Precariously perched on the edge of a cliff up there. It is more fresh and more recent than the rest. It stands out because theres no vegetation. There is no weathering of material. Those are the kinds of things you look for. There are many types of slides. There is the bedrock slides which we are looking at in is a combination of a block slide and where the material is just out of balance and is falling off. Rainfall pushes from the ground water and out of the cliff. As you can see, the slides artistic one of many types of landslides or slope failures.

Chain with a little tiny link in it which melts at a certain temperature. Thats exactly right. This would be a higher temperature. Sprinkler heads are generally 125 to 135 degrees. Or by design it could be even higher. A couple things we see at this cook station that are fire concerns, theres a frier here and if you look at this frier, you will see its separated from the flame so that the oil which is combustible is not next to the open flame. Thats a guard for it because the one head is only for that particular device, cooking device. Great. Its very effective. You can feel the make up air sweeping across and sweeping the vapor into the hood and outside. Another thing, we always look that this needs to be serviced because it is such a critical system, every 6 months and it has a state fire marshal tag that this is a licensed company to the state. Just two months ago its been serviced so its right on. Excellent. Lets find out what this lady is making over here. Hi, what are you making
The Structural Engineer might be working on a building if there is a building involved. What is your role . I am interested in the physical properties of the earth and how the earth will behave subject to different load changes. When you are building a building, you are applying a load and you are wondering if the earth will be able to supply that load. We work closely together and we come up with practical engineering solutions. This is when someone wants to build something. Also, we have a rock piece of land. We have to have a resolution. In the u. S. , about 2 3 of the population lives in areas that are prone to landslides. About 2 billion of damage occurs annually from landslides. Unfortunately, 2025 Million People die as a result of landslides o. Much of the coastline is either a bright red or a beige print th. Here we are at the base of Telegraph Hill on lombard street. This is owned by the city. Behind you is a large piece of something exposed. You are looking at a large class t
I am here with a geotechnical engineer and a geologist. We are here to talk about rockslide, rockfalls, and related issues. What is the difference between a geologist and a geotechnical engineer . And engineering geologist deals with identifying site characteristics, mapping, the grounds surface, collecting all of this data. The engineer can come up with medications and designs.
